By continuing to administer the drug, you can improve your intellectual mental function and lose urinary incontinence, such as recognizing your name, recognizing your family, and recognizing the time and place. Extremely remarkable improvement was observed in the peripheral symptoms of dementia as well as in the core symptoms of dementia such as decreased intellectual mental function. In addition, administration of DBcAP also improved the symptoms of Birkinson's disease, which had been associated with the disappearance of oHy skin and decreased muscle stiffness. Therefore, it was clinically confirmed that DBcAP improved various symptoms based on cerebral dysfunction and was useful as a cerebral function improving agent.
